I use the following code for converting Json string(strWebserviceResult) to my Object:
EntMyClass entMyClass = gson.fromJson(strWebserviceResult,EntMyClass.c
As with the other post, I would ask whether there is any way to avoid large memory usage with your app. If you can do that, it will be the most optimal solution. If your app really needs that much memory, you can try setting android:largeHeap="true"
for your application in the manifest. Here is the reference:
